Answer:
O U ⊆ A ∪ B True
O U ⊆ A ∩ B False
O A ∪ B ⊆ U True
O B ⊆ U True
O A ⊆ U True
O A ∩ B ⊆ U True
Step-by-step explanation:
To prove the first part
Remember that any set is a subset of the universal set. Therefore it is true that
Now, given any 
it is true that
Now according to the information given initially
And then you know that
Therefore 
and using double inclusion
.
Now using the information just exposed
O U ⊆ A ∪ B True
O U ⊆ A ∩ B False
O A ∪ B ⊆ U True
O B ⊆ U True
O A ⊆ U True
O A ∩ B ⊆ U True
Answer:
The answer is 4.
Step-by-step explanation:
Change 4 2/3 to 4 4/6 to match 11/6.
Add 4 4/6 and 11/6 and get 4 15/6.
Subtract 4 15/6 by 15/6 and get 4.
4 is the answer.
I hope this helps.
Have a nice day!
